A bullock team shoulders teak logs, weighing as much as 4 tons (3,629 kilograms) each, onto a cart in Mandalay, Myanmar (Burma). Many governments have banned Burmese teak, but the country still supplies an estimated 75 to 80 percent of the world's teak. Slash-and-burn harvesting threatens to wipe out forests there.

Token trees dot Brazil's Pantanal wetland where dense forest used to stand. Considered the world's largest wetland, the Pantanal is an ecological paradise that covers 54,000 square miles (140,000 square kilometers) in Brazil, Bolivia, and Paraguay, and supports thousands of animal species.

Deforestation claims a swath of tropical rain forest along the Rio Chagres river basin. The river is a primary water source for the Panama Canal, and deforestation of the surrounding rain forest causes erosion and sedimentation that can clog the canal and increase the need for dredging.
